Mifab RTS5-3 Retrofit Drain Grate Frame 5 Inch Stainless

Product Description

The MIFAB RTS5-3 is a top-set retrofit grate and frame assembly designed to replace deteriorated or mismatched floor drain grates without disturbing the existing strainer body. Constructed of stainless steel, this assembly features a 5-inch outer diameter and a two-axis adjustment system that allows vertical positioning and lateral movement to compensate for uneven or sloped finished floors. Licensed plumbers and drain service technicians install this unit as a direct drop-in replacement, making it a practical solution for drain modernization in occupied facilities where full drain replacement is not feasible.

The RTS5-3 is suited for residential and light commercial floor drain applications including showers, commercial kitchens, restrooms, and general floor areas. Installation requires removing the existing grate, setting the universal bottom ring into the recessed strainer opening, and securing it with the existing strainer screws. The grate and frame then adjust vertically and side to side to align flush with the finished floor surface, eliminating trip hazards and water pooling at the drain edge.

Key Features

• Stainless steel construction for corrosion resistance in wet floor environments
• 5-inch outer diameter top-set design drops into existing strainer body without modification
• Adjusts both vertically and laterally to accommodate uneven or out-of-level floors
• Universal bottom ring secures with existing strainer screws — no new hardware required
• Retrofit design minimizes downtime and eliminates the need to open the floor slab

Compatibility

Designed to replace 5-inch diameter grates from Zurn, Smith, Josam, Wade, Watts, and MIFAB floor drain strainer bodies.

Installation Notes

Installation is performed by a licensed plumber or qualified drain service technician. Shut off water supply to the area and verify the floor is dry before beginning work. Remove the existing grate and inspect the strainer body for damage or debris before seating the universal ring. Follow applicable plumbing codes including IPC requirements for floor drain accessibility and finish-floor elevation in wet areas.
